在一个vue页面中有时候内容会很多,为了方便编写查看,可以分为多个子组件,最后在父组件中引入对应的子组件即可。
下面这个是父子组件通信中的一个具体实例:新增、修改弹框。 子组件中主要写了关于新增、修改的弹框,
子组件:
1.弹框:
<div class="newDocuments"> <div class="newDocuments_center"> <div class="center_header"> <div class="header_left">{{ headers }}</div> <div class="header_right"> <div @click="cancel" style="font-size:20px;">x</div> </div> </div> <div class="center_center"> <el-form :model="form" :rules="rules" ref="form" label-width="120px" class="demo-ruleForm"> <el-form-item label="日期" style="width:422px;height:51px;"> <el-input v-model="form.date" autocomplete="off"></el-input> </el-form-item> <el-form-item label="姓名" style="width:422px;height:51px;"> <el-input v-model="form.name" autocomplete="off"></el-input> </el-form-item> <el-form-item label="省份" style="width:422px;height:51px;"> <el-input v-model="form.province" autocomplete="off"></el-input> </el-form-item> <el-form-item label="市区" style="width:422px;height:51px;"> <el-input v-model="form.city" autocomplete="off"></el-input> </el-form-item> <el-form-item label="地址" style="width:422px;height:51px;"> <el-input v-model="form.address" autocomplete="off"></el-input> </el-form-item> <el-form-item label="邮编" style="width:422px;height:51px;"> <el-input v-model="form.zip" autocomplete="off"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="submitForm(‘form‘)" v-if="headers == ‘新增‘">立即添加</el-button> <el-button type="primary" @click="submitForm(‘form‘)" v-else>立即修改</el-button> <el-button @click="cancel">取消</el-button> </el-form-item> </el-form> </div> </div> </div>
2.接收的数据以及需要依靠父组件的点击事件
props:["modify", "headers"], cancel() { this.$emit("cancel") }
3.新增、修改时弹框显示的内容需要进行监听
watch: { modify: function(){ this.form = this.modify; } },
父组件:
1.引入子组件:
<children v-show="addTo" @cancel="cancels" :modify=‘modify‘ :headers=‘headers‘></children> import children from ‘./father/children‘ components: { children, },
2.定义需要传给子组件的数据:
modify: ‘‘, headers: ‘‘,
3.点击新增、修改按钮时传对应的数据给子组件:
addData(){ this.addTo = true; this.modify = { date: ‘‘, name: ‘‘, province: ‘‘, city: ‘‘, address: ‘‘, zip: ‘‘, }; this.headers = ‘新增‘; }, editData(row){ this.addTo = true; this.modify = row; this.headers = ‘修改‘; }, cancels(){ this.addTo = false; }
注意:
父组件向子组件中传值使用prop,子组件中需要使用事件时使用emit向父组件传,总的来说,子组件中用到的数据以及事件都是依靠父组件得来的。
